How to vertically center a container in Bootstrap?

I'm looking for a way to vertically center the container div inside the jumbotron and to set it in the middle of the page.

The .jumbotron has to be adapted to the full height and width of the screen. The .container div has a width of 1025px and should be in the middle of the page (vertically center).

I want this page to have the jumbotron adapted to the height and width of the screen along with the container vertically center to the jumbotron. How can I achieve it?

.jumbotron {
  height:100%;
  width:100%;
}
.container {
  width:1025px;
}
.jumbotron .container {
  max-width: 100%;
}

The Flexible box way

Vertical alignment is now very simple by the use of Flexible box layout. Nowadays, this method is supported in a wide range of web browsers except Internet Explorer 8 & 9. Therefore we'd need to use some hacks/polyfills or different approaches for IE8/9.

In the following I'll show you how to do that in only 3 lines of text (regardless of old flexbox syntax).

Note: it's better to use an additional class instead of altering .jumbotron to achieve the vertical alignment. I'd use vertical-center class name for instance.

Example Here (A Mirror on jsbin).

<div class="jumbotron vertical-center"> <!-- 
                      ^--- Added class  -->
  <div class="container">
    ...
  </div>
</div>

.vertical-center {
  min-height: 100%;  /* Fallback for browsers do NOT support vh unit */
  min-height: 100vh; /* These two lines are counted as one :-)       */

  display: flex;
  align-items: center;
}

Important notes (Considered in the demo):

1. A percentage values of height or min-height properties is relative to the height of the parent element, therefore you should specify the height of the parent explicitly.

2. Vendor prefixed / old flexbox syntax omitted in the posted snippet due to brevity, but exist in the online example.

3. In some of old web browsers such as Firefox 9 ^{(in which I've tested)}, the flex container - .vertical-center in this case - won't take the available space inside the parent, therefore we need to specify the width property like: width: 100%.

4. Also in some of web browsers as mentioned above, the flex item - .container in this case - may not appear at the center horizontally. It seems the applied left/right margin of auto doesn't have any effect on the flex item.
   Therefore we need to align it by box-pack / justify-content.

For further details and/or vertical alignment of columns, you could refer to the topic below:

The traditional way for legacy web browsers

This is the old answer I wrote at the time I answered this question. This method has been discussed here and it's supposed to work in Internet Explorer 8 and 9 as well. I'll explain it in short:

In inline flow, an inline level element can be aligned vertically to the middle by vertical-align: middle declaration. Spec from W3C:

> middle
> Align the vertical midpoint of the box with the baseline of the parent box plus half the x-height of the parent.

In cases that the parent - .vertical-center element in this case - has an explicit height, by any chance if we could have a child element having the exact same height of the parent, we would be able to move the baseline of the parent to the midpoint of the full-height child and surprisingly make our desired in-flow child - the .container - aligned to the center vertically.

Getting all together

That being said, we could create a full-height element within the .vertical-center by ::before or ::after pseudo elements and also change the default display type of it and the other child, the .container to inline-block.

Then use vertical-align: middle; to align the inline elements vertically.

Here you go:

<div class="jumbotron vertical-center">
  <div class="container">
    ...
  </div>
</div>

.vertical-center {
  height:100%;
  width:100%;

  text-align: center;  /* align the inline(-block) elements horizontally */
  font: 0/0 a;         /* remove the gap between inline(-block) elements */
}

.vertical-center:before {    /* create a full-height inline block pseudo=element */
  content: " ";
  display: inline-block;
  vertical-align: middle;    /* vertical alignment of the inline element */
  height: 100%;
}

.vertical-center > .container {
  max-width: 100%;

  display: inline-block;
  vertical-align: middle;  /* vertical alignment of the inline element */
                           /* reset the font property */
  font: 16px/1 "Helvetica Neue", Helvetica, Arial, sans-serif;
}

WORKING DEMO.

Also, to prevent unexpected issues in extra small screens, you can reset the height of the pseudo-element to auto or 0 or change its display type to none if needed so:

@media (max-width: 768px) {
  .vertical-center:before {
    height: auto;
    /* Or */
    display: none;
  }
}

UPDATED DEMO

And one more thing:

If there are footer/header sections around the container, it's better to position that elements properly (relative, absolute? up to you.) and add a higher z-index value (for assurance) to keep them always on the top of the others.

Update 2021

Bootstrap 5 still use flexbox, so the methods of vertical centering are the same as Bootstrap 4...

Bootstrap 4 use flexbox, so the method of vertical centering is much easier and doesn't require extra CSS.

Just use the d-flex and align-items-center utility classes..

<div class="jumbotron d-flex align-items-center">
  <div class="container">
    content
  </div>
</div>

http://codeply.com/go/ui6ABmMTLv

Important: Vertical centering is relative to height. The parent container of the items you're attempting to center must have a defined height. If you want the height of the page use vh-100 or min-vh-100 on the parent! For example:

<div class="jumbotron d-flex align-items-center min-vh-100">
  <div class="container text-center">
    I am centered vertically
  </div>
</div>

Also see: https://stackoverflow.com/questions/42252443/vertical-align-center-in-bootstrap-4

add Bootstrap.css then add this to your css This Is the Css

html, body{height:100%; margin:0;padding:0}
 
.container-fluid{
  height:100%;
  display:table;
  width: 100%;
  padding: 0;
}
 
.row-fluid {height: 100%; display:table-cell; vertical-align: middle;}
 


.centering {
  float:none;
  margin:0 auto;
}

Now call in your page

<div class="container-fluid">
    <div class="row-fluid">
        <div class="centering text-center">
           Am in the Center Now :-)
        </div>
    </div>
</div>

In Bootstrap 4:

to center the child horizontally, use bootstrap-4 class:

justify-content-center

to center the child vertically, use bootstrap-4 class:

 align-items-center

but remember don't forget to use d-flex class with these it's a bootstrap-4 utility class, like so

<div class="d-flex justify-content-center align-items-center" style="height:100px;">
    <span class="bg-primary">MIDDLE</span>    
</div>

Note: make sure to add bootstrap-4 utilities if this code does not work

I know it's not the direct answer to this question but it may help someone

My prefered technique :

body {
  display: table;
  position: absolute;
  height: 100%;
  width: 100%;
}

.jumbotron {
   display: table-cell;
   vertical-align: middle;
}

Vertically align center with bootstrap 4

Add this class: d-flex align-items-center to the element

Example

If you had this:

<div class="col-3">

change it to this:

<div class="col-3 d-flex align-items-center>

for bootstrap4 vertical center of few items

d-flex for flex rules

flex-column for vertical direction on items

justify-content-center for centering

style='height: 300px;' must have for set points where center be calc or use h-100 class

then for horizontal center div d-flex justify-content-center and some container

so we have hierarhy of 3 tag: div-column -> div-row -> div-container

     <div class="d-flex flex-column justify-content-center bg-secondary" 
        style="height: 300px;">
        <div class="d-flex justify-content-center">
           <div class=bg-primary>Flex item</div>
        </div>
        <div class="d-flex justify-content-center">
           <div class=bg-primary>Flex item</div>
        </div>
      </div> 

If you're using Bootstrap 4, you just have to add 2 divs:

.jumbotron{
  height:100%;
  width:100%;
}

<script src="https://code.jquery.com/jquery-3.2.1.slim.min.js"></script>    
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/js/bootstrap.min.js"></script>
<link href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/css/bootstrap.min.css" rel="stylesheet"/>

<body>
  <div class="jumbotron">
    <div class="d-table w-100 h-100">
      <div class="d-table-cell w-100 h-100 align-middle">
        <h5>
          your stuff...
        </h5>
        <div class="container">
          <div class="row">
            <div class="col-12">
              <p>
                More stuff...
              </p>
            </div>
          </div>
        </div>
      </div>
    </div>
  </div>
</body>

The classes: d-table, d-table-cell, w-100, h-100 and align-middle will do the job

Give the container class

.container{
    height: 100vh;
    width: 100vw;
    display: flex;
}

Give the div that's inside the container:

align-content: center;

All the content inside this div will show up in the middle of the page.
